Clitocybula

Clitocybula is a genus of mushroom-forming fungi in the family Porotheleaceae but was originally classified within Marasmiaceae. The genus was circumscribed by Georges Métrod in 1952. Species in the genus are commonly known as "coincaps".

Description
Clitocybula fruit bodies are small- to medium-sized, with a morphology ranging from clitocyboid, collybioid, mycenoid, pleurotoid, to omphalinoid. Gills are decurrent, and the stipe is cylindrical and equal in width throughout its length. Clitocybula spores are smooth, ellipsoid to roughly spherical in shape, hyaline (translucent), and mostly amyloid (staining with Melzer's reagent).
